Abstract
Novel silane compounds, tert.-butoxy cyclopentyl dimethoxysilane and isopropoxy cyclopentyl dimethoxysilane, are prepared by reacting cyclopentyl trihalosilane with ROH (where R stands for tert.-butyl or isopropyl group) and then with methanol, or by reacting cyclopentyl trimethoxysilane with ROH. The silane compounds are useful as a catlaytic component for olefin polymerization and as a silane coupling agent.
